Additional Details

The CDS0T23 TVS diode features a standoff voltage, which is the maximum voltage that can be applied continuously without triggering the clamping action. During a transient event, the diode quickly clamps the voltage to a safe level, protecting the downstream components. The datasheet specifies the peak pulse power, clamping voltage, and other critical parameters. When selecting a TVS diode, it is crucial to consider the expected surge current, voltage level, and response time requirements of the application. Always refer to the manufacturer's datasheet for detailed specifications and application guidelines to ensure proper protection. The SOT-23 package allows for ease of assembly and a small footprint on the PCB.
